The present invention is directed to a medical device and method for delivering a drug. The medical device includes a deformable body configured to be implanted between a first vertebra and a second vertebra for providing shock absorption and stabilization of the vertebras. The deformable body comprises an impermeable inner layer forming an interior volume and an outer layer at least a portion of which is permeable. The outer layer is at least partially outside the inner layer and forms an exterior volume between the inner and outer layers. The medical device further includes a drug reservoir connected to the deformable body and in fluid communication with the exterior volume. The medical device is capable of delivering the drug from the reservoir into the exterior volume and releasing the drug through the permeable portion of the outer layer.
